Nice Ball Gun,

If you are getting tooled up to load for that, I suggest you read (if you have not already) Ross Seyfried's piece in Double Gun Journal. He wrote a two piece series called "Pieces of Eight", one on the rifles and one on shotguns. I don't have the issue #'s here, but will dig them up if you need. There you will learn what components to collect, at least to give you a good start.

Wads are available at Clay & Game in the UK. There was also a big run of 8 Ga. Winchester primed plastic hulls a few years back. They are available here (not sure about shipping to the UK) and in the UK, but I don't remember who carried them there. The Remington plastic, some say, are much more durable and better for double rifles. We can get them in once fired condition here in the US... A third choice, since the plastics are only 3 1/4" long is to have custom brass hulls turned for your gun. You would make chamber casts (do both) and either send them or check stock dimentions with http://www.rockymountaincartridge.com/. $100 for 10, but I hear they last and last.

There is one other reloading manual/book on 8 bore shotshell loads by Tom Armbrust that may be of help. http://www.precisionreloading.com/ sells that one. He has links to sources of 8 bore components in the UK or scotland if I remember correctly. Good reference item at the least.

There is a fellow in the UK that makes great ball moulds any size you like the link is here: http://www.jt-bullet-moulds.co.uk/ I would think you would want .825-.827" but have no personal experience with smooth bores.

More than you asked, but I am trying to be all inclusive.

Good Shooting
